> Key: IGNITE-4461
> URL: https://issues.apache.org/jira/browse/IGNITE-4461
> Project: Ignite
> Issue Type: Task
> Components: hadoop
> Affects Versions: 1.8
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Fix For: 2.0
>
>
> We have special {{PartiallyRawComparator}} interface which provides nice
> speedup by removing unnecessary objects deserializations during insert into
> result multi-map. And we have a one implementation for now for {{Text}}
> class: {{TextPartiallyRawComparator}}.
> We should do the following:
> 1) Try guessing proper comparator in runtime using
> {{JobConf.getOutputKeyClass()}} property.
> 2) Add ability to disable this automatic resolution.
